Balder (also Baldr) = "lord". Son of Odin, called the Beautiful for his most renown characteristic. When dreams foretold of his death, Odin had him blessed so that no weapon could kill him. The Æsir were testing this by throwing arms of all sorts at him. However, Loki knew that the one thing Balder was not immune to was mistletoe. He then helped Hoder hurl a sprig of mistletoe at Balder, which killed him instantly. The only way to bring him back from Hel was to have all the creatures in the world weep for him. They all did, save for one old woman named Thökk. Thökk was actually Loki in disguise. Thus, Balder was forced to remain in the underworld until after Ragnarök when he returned to rebuild the earth.
Hoder = The blind god who killed Balder.
